Ministère des Transports du Québec contracted Excavation Chicoutimi Inc. to build two overpass bridges on Talbot boulevard (Road 175) in Stoneham. Menard Canada was awarded the soil improvement works under the future bridges. Vibro-replacement was selected as the appropriate technique based on the existing soil conditions.
Menard Canada proposed a Vibro Replacement top feed method for the project. Prior to soil improvement works, the peat layer was excavated and replaced by A-class type sand. Menard Canada treated over 2200 m2 during the summer of 2010 in order to improve bearing capacity and to reduce the soil liquefaction potential. Testing confirmed that the treatment fulfilled specifications and was implemented according to anticipated schedule.
